|Pinned Joints - Course: Techniques of Fitting and Assembling Component Parts to Produce Simple Units. Trainees' Handbook of Lessons|
- Drills, countersinks, reamers
Various types of drills, spiral countersinks and 90° included angle countersinks, as well as cylindrical and taper reamers are used for preparing pinned joints.
- Locksmiths hammers
The pins are driven into the bore holes by means of hand-held hammers of 200 grams to 400 grams weight. Very small pins are driven in with a riveting hammer of 50 grams to 200 grams weight.
- Light-metal hammers
Aluminium hammers are used to drive in pins which might be damaged if other hammers were used.
Aluminium hammers will not cause permanent deformations to cylindrical pins or taper pins.
- Non-ferrous metal punches
Cylindrical punches made of copper or brass are used to drive in pins which might be damaged if a locksmiths hammer were used. Punches are mostly used where access to pins is difficult.
Cylindrical drifts made of non-ferrous metal or steel are used to drive pins out of their holes.
- Clamping devices
Several types of clamping devices are used to clamp the component parts before and during joining operations.
Any kind of unhardened steel plate can be used as a support for driving in or driving out pins.
